SAFETY-PIN.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed July 10, 1913. Serial No. 778,281.

To all whom it may concern:

Be it known that I, WILLIAM F. SrENon, a citizen of the United States,and a resident of Rochester, in the county of Monroe and State of NewYork, have invented a new and Improved Safety-Pin, of which thefollowing is a full, clear, and exact description.

My present invention relates to safety pins, and more particularly tothat character of safety pin which is provided with a guard inconnection with the usual coil at one end thereof in order to preventthefabric through which the pin is passed from working back into the coiland becoming caught, the object of my invention being directed to theprovision of such a guard as will be simple and inexpensive tomanufacture,

adapted to ready insertion and securance, without interfering with thenormal action of the pin spring, and without projecting edges or partssuch as would tend to fray or tear adjacent portion of the fabric inconnection with which the pin is used. The means by which I accomplishthese objects I have clearly shown and will now proceed to describe inrespect to the accompanying drawing, in which Figure 1 is a sideelevation of a safety pin provided with my improvements; Fig. 2 is asectional view therethrough taken on the line 2-2 of Fig. 1; Fig. 3 is asimilar view taken on the line 33 of Fig. 1; Fig. 4 is a plan view ofthe guard disk removed; Fig. 5 is a. transverse section on the line 5-5of Fig. 1.

Referring now to these figures, A represents the usual form of safetypin, consisting of a frame a carrying at one end a pin point housing a,and having its opposite end connected to the pin bar a? by means of acoil a the single convolution of which is inclined as most clearly shownin Fig. 2.

In accordance with my invention I provide a guard disk B ofsubstantially the same diameter as the convolution of the coil a withinwhich the disk B is disposed, as clearly shown in Figs. 1, 2 and 3, thestraight edge I) of this disk abutting the inner portion of theconvolution, and the remaining edge portion of the disk being confinedbetween the convolution of the coil and the adjacent ends of the frameand pin bars a and In this manner projecting portions are eliminated andno portion of the guard is exposed to endanger fraying and tearing ofthe fabric through which the safety pin is fastened. In order toeffectively secure and prevent removal of the disk B from the positionstated, I preferably distort the same within the convolution of the coila and in a lateral direction by a sharp bending, as indicated at b andmost clearly shown in Fig. 2, so that a portion thereof extends or isdeflected laterally from the plane of the coil 0?, and being within thecoil, accidental displacement of the disk is prevented. It may be alsoseen by reference to Fig. 2 that the edge I) of the guard disk, thoughstraight as viewed in plan, is necessarily curved or ogee shaped, asshown in Fig. 5, in order that the remaming portion of the disk edgeshall follow and be gripped between the convolution of the coil and theframe and pin bars, as before mentioned, requiring that the straightedge extend diagonally across the forward or inner portion of the spring0011- volution at a point within the coil.

It may be readily seen that the disk I propose is not only simple in itsstructure and adapted for ready disposition and securance in place, butthat by its particular structure and location the guard which I proposewill neither interfere with the action of the spring nor with the goodsor fabric in connection with which the safety pin is used.

Having thus described my invention, I claim as new and desire to secureby Letters Patent *1. The combination with a safety pin comprising frameand pin bars having a connecting coil at one end, of a guard platedisposed within the coil and spanning the open space across the samewith its edge engaged between the convolution of the coil and theadjacent portion of the frame and pin bars, and having its bodylaterally distorted inside of the coil convolution, whereby to preventdisplacement thereof.

In a safety pin, the combination with the frame and pin bars andspring coil connecting the same at one end, of a guard comprising apiece of metal associated with In testimony whereof I have signed my thep111 bar and preventing the entrance of name to this specification inthe presence of fabric between sald bar and the spring 0011, twosubscribing witnesses.
